There was a targeting call in the Iowa st Oklahoma game where the offensive player lowered his helmet into the defensive player a split second before contact, targeting was called on the field. Lucky for the player it was overturned with replay, but I believe this is the biggest issue with the rule.
Until offensive players start being penalized for ducking their heads injuries are going to happen and defensive players are going to get screwed on ejections.
No, it wasn't at all. Targeting requires crown of the helmet, some form of launch or crouch into the player, and using more or extra force than was required in the normal course of making a tackle or hit. All 3 have to be present for it to be targeting. Only the crown of the helmet was involved in it.
